Summary

On the way to a sustainable energy supply, it is necessary to be able to store surplus green energy. This energy can be stored in the form of hydrogen and oxygen via electrolysis. Various options are available for reconversion, the WTZ Roßlau has focused on the combustion engine. Until now, the internal combustion engine has been at a disadvantage compared to the fuel cell due to emissions and its efficiency. However, if the engine is operated in a closed cycle, as in the argon power cycle, and the air is replaced by an inert working gas, both disadvantages can be compensated.

The isentropic exponent κ of the selected inert gas and the compression of the test engine have a direct influence on the theoretical efficiency. In the experimental investigations, these variables were therefore analysed by varying the compression and the inert gas regarding their influence on the efficiency and the combustion stability.
